HEEL-ATTAGHING MACHINE.

Specification of Letters Patent.

Application filed January 16, 1911. Serial No. 602,884.

T all 1072 0m it may concern Be it known that JOHN Beverly, in thecounty of Essex and State of Massachusetts, insane, invented certainImprovements in Heel-Attaching Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings indicating likeparts in the several figures.

This invention relates to heel attaching machines.

The invention is shown as embodied in a machine of the type known as theNational heeling machine, in which the shoe is supported upon a suitablejack or work-support in an inverted position, the heel blank to beattached is placed on the shoe by the operator, and when the machine isstarted a reciprocatory cross-head carrying awls and drivers is firstmade to descend in order that the awls may form holes in the heel, andthen to descend again to cause the drivers to drive nails through theholes thu formed and attach the heel to the shoe. In such machines, thenails are not always driven entirely into the heel but may be left withtheir ends slightly projecting in order that the usual top lift may bespanked on by a subsequent operation of the machine.

The present improvements have for their objects the elimination ofcertain objectionable features in machines of the type refered to, thesimplification of the mechanism thereof, the successive automaticattachment of heels and top lifts in a highly effective manner, and anincrease in the speed of operation of the machine.

ll ith these and other important objects in view, the inventioncontemplates the provision, in connection with the usual rcciprocatingcross head, of a series of nail drivers connected therewith which alsoconstructed to act as awls for forming openings in the heel prior to thenail driving operation. The drivers have imparted to them two strokes ineach cycle of operations, first a short stroke to prick the heel, andthen longer stroke to drive the attaching nails, and said drivers occupypassages in the nail block which are sufficiently large in their upperportions to retain the nails during the preliminary stroke, for prickingthe heel.

E. GLLDDEN, of

When the drivers are thereafter raised, the nails are permitted to passbelow the driv- Patented Apr. 2'7, 1915. r

ers in position to be driven through the heel the attaching operation asthe dri ers are caused to descend the second time. The arrangement forthus pricking the heel upon one stroke of the drivers and forautomatically feeding the nails into position to be driven by the upwardmovement of the drivers preliminary to their attaching stroke, I regardas an important feature of the invention.

Preferably, the heel is subjected to compression while in contact withthe shoe during the pricking and heel-attaching operations by an upwardmovement of the jack, effected through toggle mechanism, which pressesblock. The nail block, which carries a top lift holder, may, andpreferably will be arranged for swinging movement and is operated insuch manner as to position the nail passages over the heel during thepricking and nail driving operations, and to locate the driver passagesto one side as the top lift holder moves in position for spanking thetop lift onto the projecting ends of the nails, and during thesemovements of the nail block the drivers are retained in the driverpassages and move laterally with the nail block.

The described movements of the nail block and top lift holder areeffected automatically in proper time relation to the movements of thecross head and the jack. In the preferred construction, this isaccomplished by two weights one of which is, through suitableconnections, arranged to move the nail block in one direction, and theother to move it in the opposite direction, said weights being lifted bythe lower cross head of the machine on the upward movement of thedrivers, and one weight retained raised, and the other released,alternately, on successive reciprocations of the cross head to firstposition the nail block passages over the heel, and to then position thetop lift holder thereover. The lateral movement of the nail block tobring the top lift holder in position following the heel attachingoperation will not be permitted until the jack descends to relieve thepressure upon the nail block, and likewise the reverse lateral movementto the heel against the templet or nail I bring the driver passages inposition for another heel attaching operation, following a'singleoperation of the treadle will start' the machine which willautomatically raise the jack, prick a heel,.drive the attaching nails,feed a top lift to the holder, lower the jack, move the nail block outof position and the top lift holder in position and bring the machine torest. A second operation of the treadle will start the machine again,and the mechanism will spank a top lift onto the projecting nails, lowerthe jack, reverse the relative positions of the-nail block and top liftholder, and stop the machine with the several parts in position foranother operation. 7

Other features of the invention than those specifically referredto,'including important details of construction and combinations ofparts, will be hereinafter more particularly described and claimed.

In the drawings: Figure l is a front elevation, partly sectional, of aheeling machine embodying the present invention, with the treadle andits connections omitted; Fig. 2 is a vertical longitudinal section ofthe machine shown in Fig. 1, including the treadle mechanism; Fig. 2 isa sectional detail view on the line y3 Fig. 2 looking in the directionof the arrow; Fig. 3 is an enlarged bottom plan view of the rotatablecarrier supporting the nail block and top lift holder; and Fig. 4 is anenlarged sectional detail view of the nail block and driver plate,showing in elevation a combined awl and driver, and a nail in a sidepocket of a driver passage. 7

The main frame 10 of the machine is pro-. vided with suitable bearings18 within which are mounted, for vertical reciprocation, the side bars12. To the upper ends of these side bars is rigidly attached a crosshead 14, and to the lower ends a cross head 16, the side bars and crossheads'constituting a rigid frame. The main frame of the machine isprovided with suitable bearings fora crank shaft 24 to which are rigidlyconnected the crank disks 52 and 80 which carry the crank 22, and apitman 20 forms a connection between the crank and the cross head 16 inorder that upon rotation of the crank shaft the frame composed of thecross heads and side bars may be reciprocated. The crank shaft 24 isprovided with two similar gears. 26, which are keyed or otherwisefastened thereto, the gears26 meshing with pinions 27 secured upon acounter shaft 28 which is mounted in suitable bearings carried by theframe 10. The counter shaft.

28 has fast thereon a gear 30 which meshes with a pinion 32 secured uponthe main driving shaft 34, which latter is supported for rotation insuitable bearings carriedby the frame 10.. The shaft 34 is shown ashaving thereon a Horton clutch 36 which is arranged between the pinion32 and the shaft 34, and may be controlled in such manner as l tooperatively connect the pinion 32 with the shaft in order to start themachine or to disconnect these parts to arrest the operation of themachine. 7 r

A treadle 38, which is fulcrumed by a stud 35 to the machine frame has acam face 39 upon its rear end which engages a cam face 37 upon thedownwardly extending arm of a lever 40, which is fulcrumed by a stud 42to theframe 1.0. The lever40 has a rearwardly extending arm 44 which isarranged to engage a shoulder on the clutch 36 and 2- thereby arrest itsmovement and-bring the machine to a stop, when the parts are as shown inFig. 2 of the drawings. Upon depression of the treadle 38, the camsurface 39 will act upon the cam surface 37, thereby raising the arm 44of the lever 40 to release the clutch, and start the'machineinoperation. The lever 40 has an upwardly extending arm 46 which at itsupper end is pro vided with a curved face 48 arranged for engagementwith a cam 50 carried by the crank shaft 24, the purpose of which willbe hereinafter explained. The crank disk 52 is provided with a camshaped depression 54 with which engages a cam roll 56 carried at thelower end of a plunger 58 which is free to slide vertically through anaperture in a table'60 which is formed as a rigid part of the main frame10 of the machine. A slide 64 carrying a jack 66 is supported upon thetable 60, and guides 62 on the table are constructed and arranged toengage the bell crank lever is pivotally connected to a link 72, whichinturn is pivoted to the jack 66, so that the arm 68 and link 72 form atoggle. WVhen the toggle is straightened the jack will be raised, andwhen the toggle is broken the jack will be permitted to descend. A thirdarm 7 4 is rigidly connected with the arms 68 and 70 of the bell crankand when the parts are in the position shown in Fig. 2 the arms 7 4 willbe engaged by a plunger 7 6, which is arranged to reciprocate through anaperture in the table 60, and carries at its lower end a cam roll whichhas bearing upon a cam-shaped projection 78 on the periphery of thesecond crank disk 80. The cam shaped depression 54 in the crank disk 52is so related angularly to the projection 78 upon the crank disk 80that, when the plunger 7 6 is raised, the plunger 58 may becorrespondingly lowered, and vice versa. It will thus be seen that asthe cam roll 56 passes from the depression 54 to the eriphcry of thedisk 52 the plunger 58 will be elevated, thereby straightening thetoggle 68, 7 2, and raising the jack to apply a preliminary pressure tothe shoe and heel supported thereon by forcing the heel against the nailblock 84; and when the cam roll on the lower end of plunger 76 ridesupon the projection 78 the cam roll 56 will occupy the de pression 54,and the toggle will be broken and the ack lowered.

Referring now to Fig. 3, the numeral 82 indicates a rotary drum orcarrier upon which are mounted a nail block and a top lift holder. Thedrum or carrier 82 is supported for rotation in a secondary frame 83which is sustained upon posts 85 erected upon the table 60, or upon anyother rigid part of the main frame 10 suitable for the purpose. As shownin Fig. 2, the drum 82 isprovided with a grooved pulley 158 which isconfined between a circumferential shoulder on the interior of the frame83 and a ring 87 which is suitably secured to said frame, the ring beingarranged below the pulley 158 and serving to thereby sustain the carrier82, it being understood that the carrier and its attached pulley are confined between the shoulder and ring in such manner as to permit of theirfree rotation, as will be more fully hereinafter described.

The nail block 84 is secured to the carrier by screws 86, which areshown as being cut away upon one side at 88 to provide a suitable amountof clearance to permit the insertion of the nail block in position. Aback gage 90 is secured upon the under side of the carrier, anddetermines the position of the rear portion of a top lift. Two gripperfingers 92 and 94 are slidably mounted upon the under side of thecarrier and are reciprocable toward and from each other, the grippersbeing provided with roughened inner surfaces to frictionally engage theside edges of a top lift. Each of the grip per fingers carries a rack,and the teeth of these racks face each otherand mesh with anintermediate idler pinion 96 to insure equal movement of the grippers inopposite directions, in order that the top lift will always be centered.A spring 98 connects the gripper fingers, and acts with a tendency tomove them toward each other for yieldingly gripping a top lift, suchmovements of the grippers being suitably limited by an adjusting screw100. The drivers 102 are secured at their upper ends in a driver plate106 which is covered by a backing plate 108, thereby confining thedrivers to the driver plate, the backing plate being provided adjacenteach driver, as shown in Fig. 4, with a nail receiving aperture 116which alines with an aperture in the driver plate. Each aperture 116 isin alinement with a pocket 117 which is positioned laterally withreference to the nail driving passage in the block 84 occupied by thedriver, from which it will be seen that if nails 114 are introduced inthe apertures 116 when the drivers are in the position shown in Fig. 4,the nails will be retained in the pockets 117 until the drivers arelifted to a height suflicient to permit the nails to move by gravityinto the driver passages below the drivers. Each driver is formed at itslower end with a reduced portion 1.12 which acts as an awl to prick theheel during the initial downward movement of the cross head 14.

The driver plate is guarded in a circular groove 110 formed in asegmental guiding flange carried by a block 188, which is supported fromthe cross head 14, and the groove 110 is arranged to register with agroove 110 in the frame 83 to form a contiuation thereof. Thearrangement of these parts is such that as the carrier 82 is rotated andmoves the block 84 the drivers partake of the same movement and arealways maintained in the driver passages, and at the proper elevationtherein.

A bracket 190,'projecting rearwardly and upwardly from the machineframe, is intended to support a suitable automatic nail assorting anddistributing device which will supply nails through a foot plate 192 tothe nail passages 117 in the nail block when the latter is in itsrearmost position during the operation of spanking on a top lift.

The crank shaft 24 carries a pinion 118 which meshes with a gear 120which is loose on the counter shaft 28 and drives a cam disk having inits face a groove 122. Suitably guided for vertical reciprocation in theframe of the machine is a rod 124, carrying at its lower end a cam rollwhich runs in the groove 122, and at its upper end having a rack 126.The rack 126 meshes with a pinion 128 to which is rigidly attached asegmental gear 130, which meshes with a rack 132 connected to a suitabletop lift feeding slide 134 which is designed to feed the lowermost toplift of a stack contained in a magazine, (not shown) forwardly intoposition between the gripper fingers 92, 94. Th1s feeding operationoccurs at that point in the cycle of operations of the machine when theheel isbeing attached to the shoe, and consequently the top lift holderoccupies an appropriate position for receiving a top lift, while thenail block is positioned toward the front of the machine, as shown inFig. 2. The reciprocation of the top lift feeding slide 134 is made tooccur at the time that the heel attaching operation is being completed.The crankshaft is geared down from the driving shaft 34 so that fourrevolutions of the latter are required to effect one revolution of theformer. Thus it is necessary to hold the stop arm 44 out of engagementwith the clutch 36 during three revolutions of the shaft 34. Thisresult, is effected by the cam 50 and cooperating arm 46, as previouslydescribed, the cam being so designed that the stop arm 44 will not beallowed to fall back and engage the clutch to stop the machine until thecompletion'of the fourth revolution of the driving shaft 34.

For the purpose of oscillating the carrier 82, the following mechanismis provided. Two weights 136, 138, are guided in sleeves 140,142,supported from the frame of the machine as shown in Fig. 1. Theseweights are attached to the ends of a cord 144 which passes over pulleys146, 146, and around a pulley 148 mounted at the front end of a shaft150. The pulleys 146 and 148 are suitably supported for rotation upon arigid part of the main frame of the machine, as shown in Fig. 1.The-shaft 150'is provided at its rear end with a pulley 152, see Fig. 2,

around which passes a belt 154 which passes over pulleys 156, and thenaround the pulley 158 on the carrier 82. Pins 162, 164, projectforwardly from theweights 136, 138, pass through vertical slots in thesleeves 140, 142, and engage the top of the lower cross head 16, asshown in Fig. 2. Mounted upon the cross head 16 is an upwardlyprojecting rack 166 which meshes Witha pinion 168, supported forrotation from the main frame, to which pinion is rigidly connected anarm 170 carrying a pawl 172. A disk 174, having two ratchet teeth 176,and a crank pin 178, is rotatable about the same center as the arm 170.The crank pin 178 travels in 'a vertical slot formed in a transverselyreciprocable rod 180 which is guided in the bores of suitable bossescarried by the sleeves 140, 142, said rod being reciprocated, throughthe connections described, as the crank disk 174 is rotated. At each endof the rod 180 is a spring-pressed pin 182 which at proper times entersa corresponding recess 184 in the respective weight. 7

The crank disk 52, in which is formed a Cam recess 54 to control theoperation of'the toggle for lifting and lowering the jack, as

shown in Fig.2, is formed in two parts which permits that part ofthediskcarrying the recess 54'to be adjusted relatively to the crank 22,in'order that the movements of the jack may be changed as to theirtiming relatively to the movements of the cross head, if desired.

In the normal operation of the machine the parts are brought to rest inthe positions as shown in Fig. 2 of the drawings with the crank 22 about45 back of its lowermost position, and the drivers 102 will be slightlyraised as shown in Fig. 4. Prior to starting the machine the opera-torwill place a shoe upon the jack 66, and will position a heel blankthereon, and move the ack to its rearmost position, as shown'in Fig. 2..The operator then steps -'upon the treadle, thereby actuatingthe lever40 to raise the arm 44 and release the clutch, which will effectengagementbetweenthe driving shaft 34 and As the machine starts the thepinion 82. crank will move for a distance of 45 downward, with theresult that the cross head is first depressed to the limit of itsdownward movement while the plunger 58 is lifted, thereby straighteningthe toggle 68, 72, and applying a preliminary pressure through the jack66 to the shoe and heel by forcing the heel against the under side ofthe nail block 84. During this initial downward movement of the crosshead the drivers are actuated a suflicient distance to prick holes inthe heel. -Upon the continued rotation of the crank the cross head iselevated until the lower ends of the drivers are high enough in theirguides or passageways in the nail block to permit the nails 114, whichwere located in the pockets 117 along the sides of the passages, to fallbeneath the ends of the drivers.

As the cross head is initially raised a half rotation will be impartedto the arm 170 in a contra-clockwise direction, as viewed in Fig. 1,through the rack 166 and pinion 168. This movement of the arm 170 will,through the pawl 172 and the ratchet tooth upon the crank disk withwhich it is engaged, cause i the rod 180 to be moved toward the right asviewed in Fig. 1, withdrawing the left-hand pin 182 from the recess inthe weight 136 which said pin hadoccupied- Both weights will be elevatedby the cross head 16 as it rises, through engagement therewith of thepins 162, 164. When the cross head is raised sufficiently to permit therecess 184 in the weight 138 to aline with the spring-pressed pin 182 atthe right hand end of the rod 180,

the pin will enter the recess and lock the weight 138 in its elevatedposition. The

cross head is then lowered by the continued operation of the machine, todrive the nails through the'heel andshoe until thedrivers are inztheposition shown in Fig. 4, the heel thus being attached in the usualmanner With the heads of the attaching nails left projecting asufficient distance to permit the top lift to be spanked thereon. Duringthis movement of the cross head the'weight 136, which had beenpreviously released, will move downward, and as soon as the parts reachthe position shown in Fig. 2 so that the pressure is released by thejack, the weight will, through the connections heretofore described,impart a semi-rotation to the carrier 82 which will locate the top liftholder over the attached heel, while the nail block will occupy theposition at the rear of the machine previously occupied by the top liftholder. While in this position nails will be supplied by the nailassorting and distributing mechanism to the apertures 116 and passthence to the pockets 117, where they will be retained temporarily bythe drivers.

As above stated, a top lift has been automatically fed to the grippers92, 9 1, and the movement of the carrier just described will bring thetop lift into attaching position. The treadle 38 being again depressed,the jack will be elevated a second time through the toggle 68, 72,thereby forcing the shoe up against the top lift held by the grippers92, 94:, the top lift being in turn forced against thestationary spankerplate 186 on the under side of the carrier, thus spanking the top liftonto the projecting ends of the heel attaching nails. During the toplift spanking operation, the drivers will not be actuated sinceby therotation of the carrier 82 they have been carried out of engagement withthe block 188 upon the cross head 14, the driver plate being temporarilyreceived in the guiding groove 110, in the frame 83. The arm 170,however, will be given another semi-rotation by the rack 166 as thecross head rises preliminary to the top lift spanking operation and,through the pawl and ratchet mechanism previously described, the bar 180will be moved this time to the left as viewed in Fig. 1, so that thespring-pressed pin 182 at the left-hand end thereof will enter therecess in the weight 136, maintaining the said weight in its elevatedposition and allowing the weight 138 to fall as the cross head islowered. When the pressure is again removed from the jack the weight 138causes a reverse rotation of the carrier 82, thereby bringing it againinto position, as illustrated in Fig. 3, preliminary to starting a newcycle of operations of the machine.

The machine isprovided with a guiding and centering gage 194: which isarranged to engage the rear portion of a shoe. This gage carries arearwardly extending threaded shank 198 which is adjustably secured to abracket, which in turn is supported for vertical adjustment upon twoscrew-threaded supports 196 extending downwardly from a rigid part ofthe frame. The gage is thus arranged for adjustment in a verticaldirection, and also in a horizontal direction toward the front or therear of the machine in order to be adaptable to different requirementsof the work.

t will be seen that the machine pricks a heel, supplies and drives theattaching nails, and spanks a top lift thereon, the only manipulation bythe operative required being to position the shoe and heel upon thejack, and to impart two sucecssive depressions to the controllingtreadle, and that all of the functions of the-machine as above describedare automatically performed.

While the controlling treadle ordinarily, and as a matter ofconvenience, is depressed twice to efiect a complete cycle of operation,the operator may by retaining his foot upon the treadle cause a completecycle to be performed without bringing the machine to a stop between theheel-attaching and top lift spanking operation.

It will be understood that changes may be made in the form, proportion,or in the structural details hereinbefore described, without departingfrom the scope of the invention as defined in the following claims.
